Features of Information Technology

Features of Information Technology The Internet also known as the Net and is also a worldwide network of computers. It is made up of thousands of interconnected computer networks (a network is a group of computers connected together). A network in the Internet can be large (consisting of thousands of computers), medium (consisting of hundreds of computers) or small (consisting of just a few computers). Similarly, the computers in the network can be mainframes, minicomputers or microcomputers. All computers in the Internet cooperate and work together to provide a variety of useful services to the users. Computers in the Internet fall into two basic categories: host (servers) and terminals (browser). Users connect to the internet by subscribing to an Internet Service Provider commonly known as an (ISP). An ISP is an organisation that provides bandwidth services at some cost to clients who wish to have internet connections in their homes or offices. NetZero, ATT and Microsoft Network (MSN) are ISPs. Individuals also connect to the Internet through business firms, universities, or research centres that have designated Internet domains. Connection is done by: Traditional telephone lines and modem Broadband services which are provided by Digital subscriber line (DSL), cable satellite connections and T lines. T1 and T3 are international telephone standards for digital communications. They leased dedicated lines suitable for business or government agencies to secure guaranteed service levels. The Internet is based on the TCP/IP networking protocol suite. Every computer on the net is assigned a unique Internet Protocol (IP) address. The Internet also consists of domain naming system which stands for DNS. The (DNS) converts IP addresses to domain names . Features that define the internet The World Wide Web (WWW) EMAIL NEWS TELNET File Transfer Protocol (FTP) Internet Relay Chat (IRC) The World Wide Web (WWW) The World Wide Web Know as WWW is part of the internet that supports hypertext documents allowing users to access and navigate different types of data. It is also a web document that is encoded with HTML tags. These HTML tags allow designers to link contents via hyperlinks. Every web page has an address which is a Uniform Resource Locator which stands for (URL). Currently the Web is viewed mainly as a tool for allowing access to a large amount of published information. EMAIL This is also known as Electronic Mail and it is the reason most people stay on the internet. With the inception of the email facility people can create, send and receive email messages to one another around the globe using an email program with an email account on the internet mail server. Email clients usually contain user interfaces to display and edit text. NEWS News is another major feature of the internet. It includes hundreds of newsgroup each newsgroup hosts discussion on a specific topic. A newsgroups name indicates its users special topic of interest such as clothes, shoes, food etc. When participating in a news program you need to have a news reader program that lets you read articles that have been posted on a news server. Articles can be posted for people to read and respond to. is the worlds biggest electronic discussion forum. It provides a way for messages to be sent among computers across the entire Internet. People from all over the world participate in discussions on thousands of specific areas of interest called newsgroups What is Telnet? The Telnet protocol is often thought of as simply providing a facility for remote logins to computer via the Internet. Telnet follows a Client / Server Model. You run a piece of software on your own PC (the client) to use the resources of a distant Server Computer (host computer) Some practical uses of Telnet include: Telnet is a Protocol that lets you use the power of the Internet to connect you to databases, library catalogs, and other information resources around the world. Telnet lets you connect directly to another computer on the Internet and run programs on the computer (provided you have access permission (Username and Password). Theoretically you have a lot of power at your fingertips. Your dumb terminal or very old PC can run programs on the worlds most powerful computers. How is the Internet governed? The Internet is a democratic setup. No single organization owns or manages all the resources in the Internet. Rather, it is collectively owned and managed by thousands of organizations from around the world. Each organization owns and manages its own network, but provides services to other networks as well as receives services from them. There is no master or slave relation in the Net all users have equal standing. The Internet data traffic is carried over transcontinental high-speed backbone networks that operate in a range of 45Mbps to 2.5 Gbps. Trunk lines are owned by long-distance telephone companies called Network Service Providers or by National Government. Local connection lines are owned by regional telephone and cable television companies in the United States that connect retail users in homes and business to internet. The regional networks lease access to Internet Service Providers (ISPs), private companies, and government institutions. Each organisation pays for its own networks and its own local Internet connection services, a part of which is paid to the long-distance trunk line. Individual internet users pays ISPs for using their services and they generally pay a flat subscription fee no matter how much or how little they use the internet. The internet is not owned by any state or organisation and it has no formal management. However the internet policies are established by a number of professional organisations and government bodies including the (IAB) Internet Architecture Board that helps define the overall structure of the NET, the Internet Corporation for assigned Names and Numbers (ICANN), assigns IP addresses and the World Wide Web Consortium which sets Hypertext Mark-up Language (HTML) and other programming standards for the web. These organisations influence government agencies, network owners, ISPs and software developers with the goal of keeping the Internet operating. The Internet must also conform to the laws of the nation-states in which it operates as well as the technical infrastructure that exist within the nation-states.

Example Self Introduction

Chris Hoskins English Communication I Personal Introduction 16 April 2012 Please Allow Me to Introduce Myself As I say in the title, please allow me to introduce myself. My name is Chris Hoskins. In fact, my full name is much longer, Christopher Alan Hoskins, but I commonly use only Chris Hoskins. Most people I work with, including students, simply call me Chris. I was born in in the state of California in the USA, but I grew up near Chicago in the state of Illinois. I moved to Illinois because of my father’s job.My father was an airline pilot for United Airlines, and when he first started working for United Airlines that company sent him to Ohare Airport, near Chicago to work out of their main place of operations. When my father moved to Illinois he took me and the rest of our family to live with him there. As I grew up I lived together with my mother, father and two older brothers in a small town outside of Chicago called McHenry. Our house was located next to the Fox River, and my family often enjoyed recreation on the river, including water skiing and ice skating.As I grew up I developed a strong interest in reading and music. My interest in music led me to choose to play the violin as a hobby, and my interest in reading led me to love studying English, which in turn led me to choose teaching English as a career. I am continuing the both my hobby and career today. It is my career that led me to work at Kyoritsu Women’s University, where I now teach classes in English and academic skills. As I continue to work at Kyoritsu, I hope to be successful in helping students develop skills that allow them to achieve their future dreams.

Feminism in Macbeth

â€Å"Does Lady Macbeth Act Against the Stereotypes? † Why Lady Macbeth should appear weak when Macbeth is the one to blame for being guilty? Feminism and the breaking of some stereotypes are the major themes in Shakespeare’s play, Macbeth, as shown primarily through the character of Lady Macbeth. At first she is shown as a brave woman who is against the stereotypes and tries to access some male characteristics by forcing Macbeth to kill King Duncan, yet she hesitates in killing him herself, which reveals her innate weakness as a woman.After the death of Duncan, she feels a strong guilt over the murder of her husband’s victims which makes her sick and she becomes psychotic. Lastly, she reveals her inferior nature as a woman by committing suicide which is a proof of her weakness and the failure of acting against her nature. Lady Macbeth’s effort to access male qualities fails right after she convinces her husband to commit murder and her feeling of guilt le ads her to eventually commit suicide, which proves the stereotype and feminism in the play Macbeth.In this play, one of the major characters, Lady Macbeth, acts against her nature as a woman to assume male characteristics, in order to become the queen. When she receives a letter from Macbeth that says he is willing to kill King Duncan, she talks to the spirits in her mind and says: â€Å"Unsex me here/ and fill me from the crown to the toe/ top full of direst cruelty! † (1. 5. 46-49). In fact she wants the spirits to strip her of her feminine traits, make her strong, and let her commit a crime without regretting it in the future.With all of these dark thoughts that she has in her mind, she still tries to act nice and compassionate in the public, so that nobody can realize what plans they have. Macbeth also wants her to act this way and he thinks that â€Å"False face must hide what the false heart doth know. † (1. 7. 92). He tells Lady Macbeth that the face should hide what the â€Å"false heart† has inside, because he is aware of Lady Macbeth’s personality and he points it out by telling her: â€Å"Bring forth men-children only/ for thy undaunted mettle should compose† (1. 7. 0-81) which shows that he believes Lady Macbeth does not have a proper action as a woman and she only should have â€Å"men-children†, meaning boys. Her effort towards having the qualities of the opposite gender helps her to do what a woman would not usually do; it helps her to plan a murder and be the reason of it. After the stereotype’s been broken, the idea of women being weak and breakable comes up through the character of Lady Macbeth by showing her inability to kill King Duncan and the strong feeling of guilt over the murders which she helps to happen, and makes her mad afterward.The moment Macbeth goes to her after he kills Duncan, and seems regretful of what he did, Lady Macbeth tells him: â€Å"Had [Duncan] not resembled/ My fath er as he slept, I had done’t† (2. 2. 16-17). She says she was not able to kill Duncan herself because he reminded her of her father. Therefore her words express the strong emotions that are still within her, and are against what she wanted to become. Right from that point, she feels the regret. Even when she is telling Macbeth that â€Å"A little water clears us of this deed† (2. 2. 85), she feels guilty about the blood on her hands.She has â€Å"hand of Macbeth’s colors† but she feels â€Å"shame to wear a heart so white. † (2. 2. 82-83). After a while, the feeling of being guilty makes her mad and she starts to feel blood all over her hands, yet they were clean. Even when Gentlewoman brings a doctor to see her, she talks unconsciously about the death of Banquo and the fact that â€Å"banquo’s buried;/ he cannot come out on’s grave† (5. 1. 58-59) but she still feels â€Å"Yet [there] is a spot† (5. 1. 29) of blood . And she also feels there â€Å"is the smell of blood still/ All the perfumes of Arabia will not sweeten [her] little hand† (5. . 46-47). The effects of regression and shamefaced make her feel insecure and mad which show her weakness and unstable personality. If she could succeed to have men qualities, she wouldn’t be suffering once she was guilty over the crime. Lastly, the failure of a woman who tries to break the stereotype is shown by Lady Macbeth’s suicide. When the doctor absorbs the sickness and madness of Lady Macbeth, he warns Gentlewoman about her situation and tells her to â€Å"look after her/ remove from her the means of all annoyances/ and still keep eyes upon her† (5. . 70-72). This is a foreshadowing that explains the cause of Lady Macbeth’s death later in the play when Seyton goes to Macbeth and says â€Å"The queen, my lord, is dead. † (5. 5. 16). That is the moment when Macbeth realizes that her wife had committed suicide and soon he says: She should have died hereafter/ There would have been a time for such a word/ Tomorrow, and tomorrow, and tomorrow/ Creeps in this petty pace from day to day/ To the last syllable of recorded time. And all our yesterdays have lighted fools/ The way to dusty death. Out, out, brief candle. / Life’s but a walking shadow, a poor player/ That struts and frets his hour upon the stage,  / And then is heard no more. It is a tale/ Told by an idiot, full of sound and fury,/ Signifying nothing. (5. 5. 16-27) Macbeth’s speech is a reflection of his love for Lady Macbeth and he sees the life is nothing but a story told â€Å"by an idiot†, after Lady Macbeth’s gone. The death of Lady Macbeth makes his life meaningless and hopeless.After trying so hard for getting the power, suddenly it’s all gone. Choosing suicide for ending Lady Macbeth’s role shows the feminism very clearly, because suicide has always been considered as the action o f somebody who is weak and unable to handle the problems that she/he has got. In this play, even though Macbeth commits the crime, it’s Lady Macbeth who commits suicide and it is a prove of the stereotype that women are weak, emotional and fragile, both physically and emotionally.Accordingly, In Shakespeare’s play, Macbeth, feminism and breaking the stereotypes can be considered as the major theme which is reflected by the character of Lady Macbeth through the play. First she is shown as a strong woman and somebody who doesn’t believe in stereotypes and the ideas that woman are weaker and fragile, and she tries to act against her inferior nature as a woman as she wants the spirits to â€Å"unsex† her. In the other hand, she shows her emotional soul by hesitating in killing Duncan and once she realizes that she is the major reasons of all the murders, she gets sick and goes mad.The feeling of being guilty and having hands immersed of blood makes her commit suicide and end the pain. Obviously Macbeth feels guilty as well but he does not committed suicide which makes him seem strong and powerful. Since suicide is always being known as a matter of weakness, giving Lady Macbeth’s character an end by a suicide is a strong proof of the stereotype and feminism in this play. Macbeth is the person who feels guilty from the first moment, so why is Lady Macbeth the one who should appear fragile and weak at the end?

Essay on What Motivates Murdresses to Kill - 2069 Words

Serial Killer do not act on impulse. They are extremely organized and meticulously plan well thought out in order for them to commit their vicious crimes time and time again, as well as cover up all evidence for their actions. Serial killers, either male or female, are not born killers, they are made killers. For hundreds of years researchers have tried to understand how serial killers think. Researchers have narrowed down to three reason as to why they do the things they do. The first is socioeconomic factors, the second is biological factors, and the last is simply by individual choice. The truth is so so simple, but at the same time so puzzling. Researchers have even tried to see if there are any chromosome patterns to determine if it†¦show more content†¦According to Dr. Michael Welner (a forensic psychiatrist and professor at a New York University) â€Å"Both[serial killers and mass murders], surely, are simply multicides. The determining differential diagnostic featur e depends upon the identification of the psychological motivation of the killer. The mass murderer kills numbers of people for any one, or any combination of the normally recognised classic motives. The serial killer kills primarily for a compulsive sexual reason, often a repulsive one, Lustmord, although, just to make things more complicated, adjunctive benefits may, accidentally as it were, accrue .† A serial killer is a person who kills four people or more in a short period of time, then takes some time off to recuperate also known as a â€Å"cooling off† period. Please do not confuse a serial killer from a mass murdered. (A mass murderer murders one after the other after the other.) When undergoing an investigation, detectives can usually detect if the murderer was a male or a female. Males tend to be more violent than women. Women usually kill with poison, they try to make it look like an accident, so in another words, the female killer takes a different more subtle approach. Female serial killers follow different trends compared to the vast majority of male serial killers. The difference between male and female serial killers is that Men tend to kill and stalk victims (strangers), and women tend not to. Women
